For the heat exchange wind after heat exchanger 6 exchanges and outside non-heat exchange wind being formed to the air-conditioner air supply device 1 that mixes wind and send, the structure in its annular heat exchange wind air channel to reducing windage, reduce crushing, to reduce noise most important, and then can have influence on the air quantity of the non-heat exchange wind in outside and the temperature of mixing wind air-out that air-conditioner air supply device 1 sucks, and the structure in heat exchange wind air channel depends primarily on the relative position relation of adjacent two annular wind guiding members and the structure of wind guiding member self that forms this air channel.In this embodiment, the structure in each annular heat exchange wind air channel is as follows:
Take the first annular heat exchange wind air channel 15 is example, as the radial section structural representation of Fig. 5 is illustrated, this air channel have close air-conditioner air supply device 1 perforation air channel outlet air end 152 and away from the annular heat exchange wind of air intake 151, the first air channel 15 that connects air channel from its air intake 151 to its outlet air end 152 convergents.
Specifically, shown in Fig. 5, in the convergent portion 113 by front end annular wind guiding member 11 and formed the first annular heat exchange wind air channel 15 of the first intermediate annular wind guiding member 13, exist the inscribed circle between a plurality of convergent portion 113 surfaces and the first intermediate annular wind guiding member 13 surfaces, as inscribed circle 153,154,155 and 156, these inscribe diameter of a circles are diminishing along the direction from air intake 151 to outlet air end 152.As shown in Figure 5, inscribed circle 153,154,155 and 156 is the inscribed circles that draw to outlet air end 152 directions successively from air intake 151, and the diameter D1 of inscribed circle 153 is, meet following relation: D1>D2>D3>D4 between the diameter D3 of the diameter D2 of inscribed circle 154, inscribed circle 155 and the diameter D4 of inscribed circle 156.And, consider the difference that air supply direction changes, air intake 151 is by the air-supply wide-angle break-in of above-below direction and the air supply direction of outlet air end 152 changes less, convergent ratio between each inscribed circle diameter is preferably non-equal proportion convergent, and the reduction ratio of the inscribed circle diameter at close air intake 151 places is greater than the reduction ratio near the inscribed circle diameter at outlet air end 152 places.For example, suppose that inscribed circle 153 is the air intake inscribed circles at air intake 151 places, inscribed circle 154 is inscribed circles of next-door neighbour's inscribed circle 153, inscribed circle 156 is the outlet air end inscribed circles at outlet air end 152 places, inscribed circle 155 is inscribed circles of next-door neighbour's inscribed circle 156, between D1, D2, D3, D4, meets following relation: (1-D2/D1) > (1-D4/D3).
Same, the second annular heat exchange wind air channel 16 and the 3rd annular heat exchange wind air channel 17 are also according to arranging with the above-mentioned condition in the first annular heat exchange wind air channel 15.
After adopting the heat exchange wind air channel of said structure in air-conditioner air supply device 1, not only be beneficial to the circumferential direction air-out of heat exchange wind air channel even, and can change the direction of heat exchange wind, heat exchange wind and non-heat exchange wind are all blown out along the surface of each annular wind guiding member, effectively avoided colliding because the annular wind guiding member surface of two parts wind in connecting air channel crosses the generation that reduces wind speed, produces the problems such as noise and condensation.
